The children, a 13-year-old girl known as the “Ice Maiden” and a boy and a girl between the ages of 4 and 5, were likely sedated to keep them compliant in the death ritual, according to the authors of an analysis of the mummies published Monday (July 29) in the Proceedings of the National Academy of Sciences.
The 500-year-old mummies are among the most well-preserved samples ever discovered, mostly due to the frigid conditions of the high altitude tomb in which they were found in 1999. (See "Pneu-mummy-a" from the November 2012 issue of The Scientist for a story of previous research done on the remains.) Detailed biochemical analysis of the mummies’ hair provided a record of what substances were circulating in the blood as new hair cells formed. Led by forensic archaeologist Andrew Wilson of the University of Bradford in the U.K., researchers discovered that the children ingested alcohol and cocaine for about a year before their death, and that consumption spiked dramatically in the weeks before they were killed.
Wilson and colleagues suspect the children were marched from the Inca ...
